I figured this out on my Ukulele, so hopefully this is accurate for guitar.

Am                G           C           F
I hear your heart beat to the beat of the drums
Am        G              C         F        Am
Oh what a shame that you came here with someone 
G              C          F
And now you're here in my arms
Am             G           C                F
Let's make the most of the night like we're gonna die young

SAME FOR THE WHOLE ENTIRE REST OF THE SONG.
